Check this out...

1) Weigh your truck at all 4 wheels. We're looking for the weight at each wheel.
2) Throw some metal rods in place of the front shocks
3) Jack up the rear 10-20" or so
4) Weigh the front wheels

Now:

CGH = Center of Gravity Height
CGwb = Center of Gravity in wheelbase (from behind the front wheel centerline)
CGtrw = Center of Gravite in track width (from left side of track width)
WB = Wheel Base
TrW = Track Width
HT = Height Raised
FW1 = Front Weight before jacking
FW2 = Front Weight after jacking
RW = Rear Weight
RtW = Right Side Weight
TW = Total Weight

Having said that:

tan x = HT / squareroot( HT^2 + WB^2 )
FWc = FW2 - FW1
CGH = ( HT * FWc ) / ( TW * tan x )
CGwb = ( RW / TW ) * WB
CGtrw = (RtW / TW ) * TrW

Keep in mind CGH in from the centerline of you axles. Now you can go paint CG spots on you truck. You will roll over when your CG spot passes your wheel.
